Abstract
Compact and flexible all-optical signal processing is highly desirable in future optical networks for its high-speed processing without optical-electrical-optical conversion. Recent progress of silicon photonics and graphene has driven the increasing research interest of ultra-compact highly efficient chip-scale all-optical signal processing. In this Letter, by exploiting a graphene-silicon microring resonator (GSMR), we propose and experimentally demonstrate channel-selective wavelength conversion of multi-channel quadrature amplitude modulation (QAM) signals. Efficient selective conversion of four-channel 16-QAM signals are observed. The selective suppression ratio and bit error rate of selective conversion are studied, showing favorable operation performance. The proposed channel-selective wavelength conversion of multi-channel signals using GSMR may find various applications in future advanced optical networks for robust data management.
